Anonymous, 18 Sep 2016battery indicator function is not working, shows 100% for two days then suddenly turns off. &a... moreI am also facing the same problem. Battery shows 100percent and suddenly shuts down and then shows 0 percent when plugged in.

Apart from battery life which can't even survive 6-7 hours if you have internet on, the phone was good in every ways. The day I bought this phone it was running in Kitkat 4.0 Android OS and as it has a customized android OS by Lenovo the update for Marshmallow 5.0 Android OS was pretty late than other phones in market and it was the last update this phone had. Since then the phone has started degrading it self and I have been facing lots of issues. Anyway now I am looking forward for buying a new phone (Suggestions are welcomed).

i am using this phone when it was upgraded on lolipop 5.0. after that the phone is going disaster. it has many problems to phase like hang, keywords in center of phone not working properly.
i am sick of this phone.
its backwaas phone..........................

It was a PERFECT phone till Stupid Android 5.0 Lollipop upgrade! Until that, the phone was working like clockwork. After the upgrade the phone was lagging, turned to completely garbage, not usable phone anymore. Also I could not root the phone that time. Plus recently the wifi stopped working. There are many, many bugs and problems with this phone which made my opinion that I completely stopped trust Lenovo and will not buy any product from this Chinese Garbage!

I have this phone for the last 2 years. Amazing, but it still working good. Only bad issue about it is battery, that some times did not show correct level, but it possible to fix it wit utility. My previous phone was Vibe x and it still working. My daughter using it on stop and it is also fine:)

Very good phone considering its price and capabilities. Good cameras, nice custom Lenovo UI, fast and reliable operation.
As someone already said, it doesn't have Micro SD slot and EU version comes with one SIM slot, but that's not a big problem. It would be much better if Lenovo offered regular MTK 6595 SOC instead of downgraded 6595M or at least offered some software upgrade which would specifically unlock 6595M speeds considering CPU and GPU.
Much bigger issue than all that is that Lenovo didn't offer an upgrade to Android 5.1.1, but only to 5.0 which is full of bugs.

Well, I got an EU version of this smartphone and it does not score 49000 in Antutu 5.7. Usually it scores around 47000, highest 47865 and lowest 46272 on my device. It also appears that its CPU is nowhere near 2 GHz but 1.859 GHz. Lenovo UI is extremely limited and doesn't allow users to adjust or change important settings without rooting the device. That's a huge minus for Lenovo and for any advanced users who knows much more than just playing games or taking photos and uploading them to facebook.

@Shipra Such problems don't occur just like that. Seems that you messed up upgrade to Andriod 5.0, which is full of bugs, or you dropped your phone. Try factory reset after backing-up your data. Vibe X2 much better functions with stock android 4.4.2 Kit-Kat than with 5.0 Lollipop. I know that because I tested it with various roms and against various X2's competition which was all beaten considering the performance.
